BOTEGA, Neury J. et al. Mood disorders among medical in-patients: a validation study of the hospital anxiety and depression scale (HAD). Rev. Saúde Pública [online]. 1995, vol.29, n.5, pp. 359-363. ISSN 0034-8910. http://dx.doi.org/10.1590/S0034-89101995000500004.
The revised Clinical Interview Schedule (CIS-R) and the Hospital Anxiety and Depression (HAD) Scale were used to estimate the prevalence of mood disorders among 78 consecutive admissions to a general medical ward in a university general hospital in Brazil (43 males and 35 females; mean age = 43.2yr). Interviewers also completed a 5-point symptom severity scales for anxiety and depression. The definition of cases of anxiety [and depression] was based on two criteria: a. score > 2 on the CIS-R section of anxiety [> 4 on the CIS-R sections of depression and depressive ideas]; and b. score > 2 on the clinical severity scale for anxiety [score > 2 on the clinical severity scale for depression]. A 39% prevalence rate of affective disorders was found. Sixteen (20.5%) patients met criteria for anxiety, most of the disorders being of mild severity. Twenty-sic patients (33%) were depressed, 7 of them in a moderate degree. The HAD was easily understood by the patients. Anxiety and depression subscales had internal consistency of 0.68 and 0.77, respectively. At a cut-off point of 8/9 sensibility and specificity were 93.7% and 72.6% for anxiety, and 84.6% and 90.3% for depression. HAD items correlated positively with the respective subscales. To a lesser degree, they also correlated with the alternative subscale. Our findings confirm the high prevalence of mood disorders among medical in-patients. In clinical practice, the HAD may have a useful role in detecting those patients requiring further psychological care.
